Histograms of B − R colors from selected H_R(α) ranges: a) all the 253 objects. Taken globally do not exhibit statistical evidence for bimodality, which was known to exist among Centaurs. b) The 124 “small” objects, with . Evidence for bimodal behavior is clear and still present when removing Centaurs. c) The 38 “large” objects, with . A bimodal behavior is shown but it loses the statistical significance without the “Haumea collisional family” objects. d) The 91 “intermediate” size objects, 6.8 > H_R(α) > 5.0. Regardless of the apparent small gap at B − R ~ 1.3 there is no statistical evidence for two separate groups.
